The formula to find the number of chairs in each row is m = x ÷ n,
where
m - the number of chairs,
n - the number of rows,
x - the number of people.
If 60 people attend the meeting and each row has 4 chairs, there are 15 <span>rows.
</span>This is assumed using the above formula:
m = x ÷ n
If:
x = 60
m = 4
Then:
4 = 60 ÷ n
⇒ n = 60 ÷ 4
<span>⇒ n = 15</span>

V = Bh
Answer:
44
Step-by-step explanation:
This is called the Tribonacci sequence. In this sequence, you add the last 3 numbers together to get the next number in the sequence.
For example, 0+1+1=2, 1+2+4=7, 4+7+13=24 and so on.
7+13+24=44
44 is the next number in the sequence
The number of ways you can choose "r" things from a larger set of "n" things:
n! / r! * (n -r)! =
49! / 6! * (43!) =
49 * 48 * 47 * 46 * 45 * 44 * 43! / 6! * 43! =
49 * 48 * 47 * 46 * 45 * 44 / 6 * 5 * 4 * 3 * 2 =
49 * 47 * 46 * 45 * 44 / 5 * 3 =
49 * 47 * 46 * 3 * 44 =
<span><span><span>13,983,816
</span>
</span>
</span>
So it is 1 in 13,983,816<span> and
p = </span>
<span>
<span>
<span>
0.00000007151123842019
</span>
</span>
</span>
So, it is true.
